Urinary tract infection (UTI) is one the most common infection in children. In case of undiagnosed, UTI could have co-morbidities especially in children 2-24 months of age. Incorrect over diagnoses could also be lead to unnecessary examinations or potentially harmful treatment. Therefore, we revised our UTI approachment schema in 2016 by goal of reducing use of invasive screening tools. Herein, we would like to share our preliminary results of the cohort followed by the new UTI guide.

Material and methods:

All the patients in 2-24 months of age, have first febrile UTI included the study from October 2016. UTI follow-up schema was given in Figure 1. All urine specimens were obtained using catheterization method. Positive urine analysis, significant bacteriuria [Culture (+)], definitive UTI and suspected UTI were described in Figure 1.

Results:

There was total 108 patients (55 female,%49.7). 79 (73.14%) of the patients were diagnosed definitive UTI. The mean diagnosis age was 7.35 months (range:2-24)(p>0.05). Mean body temperature was recorded 39.120C. Most common complaints were vomiting and diarrhea. Body weight, height, serum urea, creatinine and white blood count were detected similar between groups. E.coli was the most common pathogen in both groups. Although in significant, CRP level was higher in suspected UTI group, as well as procalcitonin level was higher in definitive UTI group. 88 (81.48%) and 95 (97.96%) of the patients had normal US and DMSA, respectively. In follow-up, 69.44% of the patients had no UTI. Overall UTI frequency was calculated 0.89 episode/year. There was no need for VCUG in 59.26% of cohort.

Conclusions:

Our preliminary results showed that we have reduced UTI frequency in comparison with our previous studies. Therefore, also importantly, the performing rate of VCUG reduced to 40% in our new guide. Although, it is recently small cohort, our preliminary results are encouraging.
